Flora and fauna of underground world


Man is not the only one living being who venture into the underground world. Plants are growing at the beginning of the galleries and animals are living deeper in the darkness. Bats remain the most famous inhabitants. They are sleeping during the day in the gallery and hunting insects outdoor during the night. From bats and their guano there is a complete food chaine with bacteria, arachnids and insects.
